As Miami-Dade County prepares to reopen in stages, the Miami-Dade Water and Sewer Department (WASD) is reminding businesses to flush their internal plumbing systems prior to allowing access to the public.

Because many businesses have been closed during the State of Emergency, water has not been used and remained sitting in their pipes for multiple weeks.

“Stagnant or standing water can cause conditions that increase the risk for growth and spread of Legionella and other biofilm-associated bacteria,” said WASD Director Kevin Lynskey. “WASD continues to operate and provide high quality drinking water to our 2.3 million customers, but our system doesn’t interact with private plumbing systems once the water has been delivered. We want to ensure the safety of your building water system and devices after a prolonged shutdown.”

“The Centers for Disease Control and Prevention (CDC) has produced a set of guidelines for businesses to follow so that they prepare their plumbing systems and devices before reopening their businesses,” said Samir Elmir, Environmental Administrator for the Department of Health (DOH) in Miami-Dade County.

“This includes but is not limited to buildings’ plumbing hot and cold-water systems, cooling towers, hot tubs/pool spas, water heaters, and decorative fountains. Following the CDC guidelines can greatly reduce chances for Legionella and other opportunistic waterborne microbes from developing within plumbing systems and devices.”

Businesses owners with questions regarding the CDC recommendations or water quality of their plumbing system can call the DOH at 305-324-2400.

It is the priority of the Miami-Dade Water and Sewer Department to provide safe, reliable service to its customers. For additional information about Department services and programs, visit the WASD website.
